Tests Across Suite584+
> SELECT_PROJECT
6-agent LangGraph system that researches companies and drafts targeted outreach.
ROLE :: Solo - design, agents, guardrails, tests
PROOF :: 368+ tests · 4-layer guardrail system
System_Architecture
  • 6-agent stateful DAG with parallel fan-out/fan-in (LangGraph)
  • Agentic RAG pipeline: Tavily scrape → Qdrant index → LLM synthesis
  • ReAct sub-graph GitHub analyst with 7 tools and 4-layer hallucination guardrails - the agent only acts on repos and labels it has actually verified
  • Human-in-the-loop graph interrupt for target selection
  • Pydantic structured outputs with retry-and-fallback; tenacity proxy retries only transient errors (429/5xx)

Building agents
that ship?

I take on agentic systems and backend work where reliability matters. Remote-first from India, with a daily overlap window for US and EU teams.
